AV amplifiers and HIFI amplifiers are the two most common devices in the speaker equipment market. For many small white users, he may not know "what AV amplifier, what is hifi/target=_blank>HIFI amplifier", then he should How to choose the amplifier you need? Don't worry, today, the author said to everyone: the difference between AV amplifier and hifi/target=_blank>HIFI amplifier, and which amplifier is good. AV amplifier What is hifi/ target=_blank>HIFI amplifier Hifi/ target=_blank>HIFI amplifier 3, the sound atmosphere is different Floor-Standing Transfer Box,Outdoor Floor-To-Ceiling Transfer Box,Outdoor Fiber Optic Cable Transfer Box,Specialized Fiber Optic Cable Transfer Box Shenzhen Jingtu Cabinet Network Equipment Co., LTD , https://www.jingtucabinet.com
What is an AV amplifier?
AV amplifier's A (audio) means audio, audio, V (video) means audio, image, so AV amplifier is a combination of audio and video signal processing audio amplifier, emphasizing the sound field atmosphere, dedicated to home theater . 
Hifi/ target=_blank>Hi-Fi of HIFI amplifier is the abbreviation of English Hight-Fidelity, which is literally translated as high fidelity. It requires the audio equipment to zoom in and process the sound signal indicators without distortion during the playback process. Restore the original appearance of the sound source, emphasizing the original taste, specifically for listening to music, such as classical music.
The difference between AV amplifier and hifi/ target=_blank>HIFI amplifier
In the above, we briefly understand the "what is the AV amplifier, what is the hifi / target = _blank > HIFI amplifier", and recognize the difference between the AV amplifier and hifi / target = _blank > HIFI amplifier: the former is mainly For the home theater field, you need audio + video equipment, while the latter only need to provide audio equipment, focus on listening to music, then, besides, what is the difference between AV amplifier and hifi / target = _blank > HIFI amplifier? Let's continue reading.
1, the number of channels is different
The AV amplifier has 4-9 channels that drive multiple speakers to form a surround sound field. For example, the Dolby AC-3 requires 5.1 channels. The Hi-Fi function is usually two channels when playing, that is, the signals of the left and right channels are amplified, and the left and right two groups of speakers are pushed, thereby forming a stereo sound field.
2, the parameter indicators are different
The parameters of the AV power amplifier mainly include output power, harmonic distortion, signal-to-noise ratio, frequency range, rated impedance and damping coefficient, especially highlighting the channel isolation, delay time range, various sound field modes and other indicators. More indicators on the video section. Hi-Fi amplifiers have these parameters, but they emphasize harmonic distortion and signal-to-noise ratio. 
The AV power is placed in the sound mode as the main design purpose, emphasizing the sense of position of the sound, simulating the atmosphere of the listening environment, and the Hi-Fi function is designed with high fidelity in the way of sound reproduction, paying attention to the original taste. Amplify the signal from the signal source, mainly used to enjoy music, vocals, etc., and pursue the true effect of the sound.
AV amplifier can be used as hifi / target = _blank > HIFI amplifier? AV amplifiers combine audio + video two signal processing amplifiers, and hifi / target = _blank > HIFI amplifiers only audio amplifiers, then we can use AV amplifiers instead of hifi / Target=_blank>HIFI amplifier? The answer is no, for the following three reasons.
1. The AV power is not enough when playing large dynamic range music. The output power of the AV amplifier in the two-channel state is larger than that in the four-channel state. At this time, the music with a large dynamic range is used for audition, and it is obvious that the power is not enough. The Hi-Fi amplifier is calm.
2, AV amplifier wiring affects the sound quality AV amplifier to set a variety of video, audio ports, access to multiple sets of audio and video signal sources, resulting in a large number of signal lines, easily lead to signal interference. The original high-frequency components of the high-quality signal source are attenuated or interfered, so that the listener can not appreciate the high-fidelity effect.
3, AV amplifier's fluorescent screen will interfere with the sound quality AV power amplifier panel is equipped with a large fluorescent display, the character display under the driving of the pulse signal, will radiate a lot of electromagnetic interference to the surrounding, significantly affecting the sound quality.
It is said that AV amplifier can not replace hifi / target = _blank > HIFI amplifier, but it does not have to be so true, if your requirements for sound quality is not too high, AV amplifier can also be used as hifi / target = _blank > HIFI amplifier, such as security The bridge's AV amplifier, which is recognized in the industry as a power amplifier device for both home theater and music appreciation. Of course, the final result is not so ideal compared to the professional hifi/target=_blank>HIFI amplifier.
